class_docstr: Shuffling implements a shuffling algorithm. Items can be added to the shuffling buffer and removed in a
  different order as defined by the concrete shuffling algorithm. A shuffling buffer is intended to be used from
  a single thread, hence, not thread safe.
docstr: Adds multiple items to the buffer.
  
  :param items: items to be added to the shuffling buffer.
  :return: None
